Description

Technical Field

[0001] The present application relates to the technical field of climbing frames, and in particular to an anti-fall mechanism for a climbing frame. Background Art

[0002] Climbing frame, also known as attached lifting scaffolding, is a large-scale mechanical equipment used for construction protection in the construction field. It can rise or fall with the building to provide protection for the construction of the building facade. Because it is a high-rise building, the safety of the frame lifting is extremely important. How to set up a fall prevention mechanism during the frame lifting process is related to the life safety of construction workers.

[0003] At present, most anti-fall mechanisms are hinged to support rods on the wall. When the climbing frame falls rapidly, the support rods can support the cross bars welded on the climbing frame to prevent the climbing frame from falling. However, the impact force generated when the climbing frame falls will directly act on the support rods and the cross bars. Once the support rods and the cross bars are deformed and damaged by external forces, the anti-fall mechanism will fail and its reliability will be greatly reduced. In order to reasonably improve this problem, the present application proposes an anti-fall mechanism for a climbing frame. Utility Model Content

[0004] The purpose of the present application is to solve the technical problem that most anti-fall mechanisms are hinged support rods on the wall.

Once the support rods and the cross rods are deformed and damaged by external forces, the anti-fall mechanism will fail and the reliability will be greatly reduced. The present application provides an anti-fall mechanism for a climbing frame.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figure 1-Figure 5 As shown, an anti-falling mechanism of a climbing frame proposed in one embodiment of the present application includes:

[0028] The mounting seat 1 is plate-shaped and can be fixed on a fixed surface of a frame or a wall by a bolt assembly, and one side of the mounting seat 1 is symmetrically connected with a mounting plate 2, which is away from the fixed surface and vertically connected to the mounting seat 1;

[0029] The guide rail 3 is slidably matched with the two mounting plates 2. The guide rail 3 is arranged between the two mounting plates 2, away from the mounting seat 1, and slidably matched with the mounting plates 2 in the vertical direction;

[0030] The movable plate 4 is hinged on the opposite sides of the two mounting plates 2 and is arranged in an inclined shape. The guide rail 3 is provided with a contact surface 5, which extends along the length direction of the guide rail 3 and is wavy, and its concave and convex surfaces are both arc-shaped. A roller 6 is rotatably installed at the end of the movable plate 4. The end here specifically refers to the end of the movable plate 4 located at a lower position, which is movably overlapped with the contact surface 5. An elastic member 7 is provided on the mounting seat 1, which is used to drive the end of the movable plate 4 to move toward the movable plate 4. Under the action of the elastic member 7, the roller 6 can contact the contact surface 5. When the guide rail 3 moves slowly, the roller 6 can roll along the contact surface 5. When it moves to the convex surface of the contact surface 5, the elastic member 7 is slightly compressed;

[0031] Two slide grooves 8 are respectively opened on opposite sides of the mounting plate 2. The slide grooves 8 pass through the top of the mounting plate 2. The opposite sides of the slide grooves 8 are constructed with guide slopes 9. The spacing between the two guide slopes 9 gradually decreases from top to bottom. The guide slopes 9 are slidably matched with sliders 10. The sliders 10 are conical blocks. The sliders 10 are accommodated by the slide grooves 8. The opposite sides of the sliders 10 are installed with friction blocks 11. The friction blocks 11 are made of semi-metal friction materials and are friction-resistant. The friction blocks 11 are in contact with and overlap the guide rails 3.

[0032] Two transmission components 12 are respectively arranged on the mounting plate 2. The slider 10 is transmission-connected with the movable plate 4 through the transmission components 12. When the movable plate 4 rotates along the hinge point, the slider 10 can be driven to move in the slide groove 8 through the transmission components 12.

[0033] It should be specifically explained that when the roller 6 moves to a state where it contacts the convex surface of the contact surface 5 , the friction block 11 on the slider 10 does not contact the guide rail 3 ;

[0034] When the guide rail 3 falls, due to its high speed, the rapid movement of the resistance surface 5 can collide with the roller 6. Under the action of the impact force, the end of the movable plate 4 can move in the direction away from the guide rail 3. At this time, the end of the movable plate 4 rotates downward along the hinge point of the movable plate 4 and compresses the elastic member 7. At this time, the end of the movable plate 4 can drive the slider 10 to slide along the guide inclined surface 9 from the top of the slide groove 8 to the bottom through the transmission component 12. The two sliders 10 approach each other during the sliding process, and the friction blocks 11 thereon can contact the guide rail 3. Under the action of the friction force, the guide rail 3 can drive the two sliders 10 to be further retracted inward synchronously through the friction block 11, so as to brake the guide rail 3. When the guide rail 3 is driven to move upward, the thrust of the elastic member 7 when it is reset and the friction between the guide rail 3 and the friction block 11 can cooperate to drive the slider 10 to slide upward, so as to release its restriction on the guide rail 3.

[0035] The present application adopts the design of the transmission component 12. When the guide rail 3 falls, the end of the movable plate 4 can be driven away from the guide rail 3 through the impact of the resistance surface 5 on the roller 6, and the slider 10 can be driven to slide downward through the transmission component 12. When the friction blocks 11 approach each other and contact the guide rail 3, under the action of friction, the guide rail 3 can drive the two sliders 10 to be further retracted inward synchronously through the friction blocks 11, so as to brake the guide rail 3. Compared with the traditional braking method through the support rod and the cross bar, the slider 10 and the friction block 11 will not be damaged under the impact force of the guide rail 3, so it is practical.

[0036] like Figure 2 and Figure 4As shown, in some embodiments, the elastic member 7 includes a sleeve 701 constructed on the mounting seat 1, the sleeve 701 is located between the two mounting plates 2, and an inner rod 702 is slidably fitted therein, and a compression spring 703 is provided between the two. The compression spring 703 is the abbreviation of a compression spring, which is used to provide a thrust forcing the inner rod 702 to extend out of the sleeve 701. A resistance portion 704 is provided at the end of the inner rod 702, which movably contacts the end of the movable plate 4. Under the contact of the resistance portion 704, the end of the movable plate 4 moves toward the guide rail 3, and the upper roller 6 contacts the contact surface 5. When the end of the movable plate 4 is away from the guide rail 3, the resistance portion 704 can slide on the movable plate 4 and force the inner rod 702 to retract into the sleeve 701.

[0037] like Figure 2 and Figure 4 As shown, in some embodiments, the resistance part 704 includes a horizontal plate 7041 connected to the inner rod 702, and the two ends of the horizontal plate 7041 extend toward the two mounting plates 2 respectively. The horizontal plate 7041 is symmetrically structured with a resistance block 7042, and the resistance block 7042 is hemispherical. The resistance block 7042 is close to the movable plate 4. When the movable plate 4 moves, the resistance block 7042 can resist the movable plate 4, thereby reducing the friction resistance by reducing the contact area. The design of the two resistance blocks 7042 can improve the resistance effect on the movable plate 4, which is convenient for driving the movable plate 4 to rotate.

[0038] like Figure 2 As shown, in some embodiments, a pick-up and release groove 13 is opened on the side of the mounting base 1 away from the sleeve 701, the inner rod 702 slides through the pick-up and release groove 13, a baffle 14 is installed in the pick-up and release groove 13 through a bolt assembly, and the two ends of the compression spring 703 are respectively in contact with the baffle 14 and the inner rod 702. After the baffle 14 is removed, the compression spring 703 can be taken out of the pick-up and release groove 13 for replacement.

[0039] like Figure 1 and Figure 2As shown, in some embodiments, the transmission assembly 12 includes a hinged plate 1201 hinged to the top of the mounting plate 2, a first waist hole 1202 is opened at the end of the movable plate 4, and first guide pillars 1203 are constructed on opposite sides of the end of the hinged plate 1201, and the two first guide pillars 1203 are tangential to the first waist hole 1202. When the end of the movable plate 4 moves downward under the impact of the contact surface 5, the end of the movable plate 4 is lifted. At this time, the first guide pillar 1203 can slide in the first waist hole 1202, the end of the hinged plate 1201 moves up, and the hinged plate 1201 A second waist hole 1204 is opened at the end, and a second guide column 1205 is constructed on the top of the slider 10. There is an obtuse angle between the axis of the second guide column 1205 and the extension direction of the guide slope 9, and the second guide column 1205 is tangent to the second waist hole 1204. When the end of the hinged plate 1201 moves downward, the second guide column 1205 can conflict with the inner wall of the second waist hole 1204. At this time, the slider 10 can slide along the guide slope 9. While the second guide column 1205 slides in the second waist hole 1204, it can move toward the guide rail 3 together with the slider 10.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the hinge axis of the hinge plate 1201 is close to its end, and the distance between the end of the hinge plate 1201 and its hinge axis is smaller than the distance between its end and the hinge axis. Such a design can amplify the stroke of the end of the hinge plate 1201 when the end of the hinge plate 1201 moves, so that the slider 10 can collide with the guide rail 3 at the first time it falls, thereby improving the safety performance of the device.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the two first guide pillars 1203 are connected to each other, so that the structural strength of the two first guide pillars 1203 can be improved, making it difficult for them to bend and deform during the movement of the movable plate 4.

[0042] like Figure 5 As shown, in some embodiments, a receiving groove 15 is provided on the guide rail 3, which extends along the length direction of the guide rail 3. The contact surface 5 is constructed in the receiving groove 15. The contact surface 5 can be received and protected by the receiving groove 15, so that it is not easily deformed and damaged by collision, thereby extending its service life.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
